How to Solve Troubleshoot of Sand Washer?
Sand washing machine are mainly used in building site, gravel plant, concrete dam building site of hydropower station, etc., and with features of high degree cleaning-up, reasonable structure, large capacity, low power consumption, small loss of the sands during the washing process, especially for that the drive parts of the sand washing machine are separated from water and sands. So that it has lower failure rate than the usual sand washing machine.
Sand washing machine is widely used in construction sites , gravel plants (sand plant ), concrete hydropower dam site and other industries . The machine has features of large treatment volume, high cleaning , reasonable structure, small power consumption, less sand loss( sand washing process ), and GX series sand washing machine transmission parts are related to water , sand completely isolated , so the failure rate is far much lower than the commonly used sand washing machine equipment ,which is the best choice for upgrading the industry in the sand washing machine industry.
In the process of using sand washing machine we find that motor failures often affect production ,the main faults are as follows :
1. Stator and rotor core troubleshooting .
Stator and rotor are all mutually insulated by the silicon quartet built ,which is part of the motor ‘s magnetic circuit . Stator and rotor core of damage and deformation is caused mainly by the following reasons .
a . Rolling bearing excessive wear or assembly bad,which can cause the stator and the rotor mutual friction, making the iron core surface damage,and then causing a short circuit in between silicon-steel sheet,increasing motor iron loss , making the motor temperature rise too high . When application fine file tools such as removing burr, eliminating silicon steel short sub,after cleaning,Coating with insulating paint,heating and drying. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like impact crusher, Henan Hongxing is always doing the best in products and service.rock crushers:http://www.hxjq-mill.com/products/cone_crusher.html
b . Dismounting the old winding of using excessive force ,which can cause pirates of the slot crooked , and splayed out . At this point, the application needle nose pliers, wood hammer and other tools to repair ,making tooth socket reset , and in the bad reset the gap in between silicon steel to add green shell paper , wood and other hard rubber insulation materials .
c . Due to other causes of damp core surface corrosion . At this point required a clean sanding ,after cleaning ,coating with insulating paint .
The electric motor runs slowly with the impellor after decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing launder from feeding launder, rolls with the impellor, and grinds each other. The impurity covering the sand is washing away. At the same time, add more water, the strong water flow will take away waste and some low-weight wastes from washing launder. Through the above process, the washing function is finished. The clean sand and stone is lift up by vane. When it goes up slowly, the water begins to drop through the mesh and fall back in the washing launder. On one hand, water is removed from the sand and stone; on the other hand, the water can be fully used. Finally, the sand and stone goes to the out launder from the rotary impellor to finish the washing task.
